Abstract

COVID-19 is the current day pandemic that has claimed around 1,054,604 lives globally till date. Moreover, the number of deaths is going to increase over the next few months until the pandemic comes to an end, and a second wave has also been reported in few countries. Most interestingly, the death rate among certain populations from the same COVID-19 infection is highly variable. For instance, the European populations show a very high death rate, in contrast to the populations from Chinese ethnicities. Amongst all the closed cases with an outcome (total recovered + total died), the death rate in Italy is 13%, Iran is 6%, China is 5%, Brazil is 3%, The United States of America is 2%, India 2%, Israel is 1% as of October 08, 2020. However, the percentage was higher during the early phase of the pandemic. Moreover, the global death rate amongst all the patients with an outcome is 4%. Here we have reviewed virus-transmitted various respiratory tract infections and postulated a better understanding of SARS-CoV2 using lung stem cell organoids in vitro. Hence, here we propose the strategies of understanding first the infectivity/severity ratio of COVID-19 infections using various ethnicity originated induced pluripotent stem cell-derived lung stem cell organoids in vitro. The greater the infectivity to severity ratio, the better the disease outcome with the value of 1 being the worst disease outcome. This strategy will be useful for understanding the infectivity/severity ratio of virus induced respiratory tract infections for a possible betterment of community-based disease management. Also, such a strategy will be useful for screening the effect of various antiviral drugs/repurposed drugs for their efficacy in vitro.
